Reference Standard Test MA-1040 Magnetic Analyzer

Reference Standard Test
A Reference Standard is provided to ensure that calibration of the MA1040 is accurate based on the
original specifications.
1. With the sample chamber empty, set the WEIGHT-GRAMS control to 100 grams and adjust the
ZERO control to 000.0.
2. Place the reference standard in the sample chamber. Within two to three seconds, a reading is
displayed; ignore this first reading.
3. Remove the reference standard from the sample chamber, then reinsert it; a reading is displayed
within two to three seconds. Make a note of this reading.
4. Repeat Step 3 two more times, making a note of each reading.
5. Take an average of the three readings (from steps 3 and 4). The average for the three readings
should be within 1% of the value printed on the reference standard, or ± 0.5 PPM, whichever is
greater. If the reading is outside of this range, contact Particulate Systems for assistance.
6. Remove the reference standard.
It is recommended that a reference standard test be performed at the
beginning of each work day when using the analyzer on a daily basis.
It is important that the temperature for the reference standard and analyzer be
the same. Otherwise, the reading may drift quickly and skew the reading. If this
occurs, allow the standard to remain in the chamber to equilibrate to the
temperature of the analyzer (approximately 5 - 10 minutes) before proceeding.
When not in use, do not store the reference standard in the sample chamber.
